It's a shame that Laurette Taylor's legendary stage performance as Amanda wasn't captured on film. So many actors and actresses, from Charles Durning, Ben Gazzara, Marian Seldes and Gena Rowlands to Nanette Fabray, cite her natural acting in that as their inspiration for becoming actors.
Of the three filmed versions, I like the 1974 made-for-televison version with Katharine Hepburn, Michael Moriarty, Joanna Miles and Sam Waterston best. Moriarty and Miles deservedly won Emmys for their performances while Hepburn was nominated, deservedly losing to Cicley Tyson in The Autobiography of Miss Jane Pittman. If her Amanda seems a bit too strong, it is certainly a better portrait than that of Gertrude Lawrence in the 1950 version.
Joanne Woodward was probably the best Amanda on film. She, Karen Allen and John Malkovich were good in the 1987 version, but by then the work itself seemed a bit old-fashioned and yet another film version a bit redundant. Still, Mancini's evocative score was one of his best, though, and certainly deserved a nomination over John Williams' The Witches of Eastwick. In order to deny Mancini, they had to nominate Wiliams twice, having also nominated him deserdly for Emprie of the Sun.
As for Woodward, though she certainly merited consideration, 1987 was an unusally strong year for actresses. The non-nominee I think most unfairly overlooked that year was Maggie Smith in The Lonely Passion of Judith Hearne.
